Media server operatorInteractive programmerSoftware developer

CVH Visuals, media server operator and software developer: Every pixel, on cue.

I run the media servers behind keynotes, concerts and immersive rooms — LED walls, projection blends and real-time content. I also write the software crews use to get the show right: a real-time previsualizer, pro video apps for Apple platforms, and custom firmware.

Services

From the server rack to the last row.

Media server operation, playback programming and interactive development — on site, or in pre-production before anyone loads in.

01 / PLAYBACK

Media server operation

Programming and operating playback for LED walls and multi-projector blends. Canvas and output mapping, cue stacks, timecode, backup servers and calm show-calling with the director.

  • Projection & blends
  • Timecode
  • Redundancy

02 / REAL-TIME

Interactive & real-time media

Live-rendered graphics, audio-reactive and sensor-driven content, and custom show control so the screens respond to the room instead of looping.

Previsualization

Your venue, screens and lighting rig playing the real show content in real time with Millumin PreViz, so content and staging get signed off before anyone is on site.

Show tools · Millumin PreViz

See the show before the room is built.

A real-time previsualizer I develop for Millumin. It builds the venue from the designer's drawing, maps every LED wall and projector from the show file, and plays the live output on all of it — with the lighting rig running looks alongside.

  • Live, not rendered. Syphon or NDI straight from Millumin, mapped pixel-for-pixel to each wall.
  • The rig, as hung. Moving heads from the drawing, a cue library, and Art-Net / sACN console input.
  • Any seat, any angle. Check sightlines and camera positions, then export 4K stills and fly-throughs.
